Appneanon mea January f` This invent-ion 'relates to steam separatorsand particularly to such separators to 'housed with locomotivesand thelike. In my Acopending application for patent, Serial No. 39.20@filedJune 24, 1925, I have'il'lustrated n 'and described a fluidseparator which comprises a combination 'of' baille means for breaking-up the bubbles Ain ythe steam and centrifugal separa-ting means Lforseparating the moisture from the steam. This present invention vis animprovement on that inven- -tion and particularlyin applying thatiiniention to loc'zomotives. The details of the invention as set forthin said application are not particularly essential to the presentinvention and hence are not fully set forth herein; but reference may behad to that application forsuch details'.

Of the accompanying drawings Fig; I is a side elevation of arsteamseparating system which embodies the features of my invention, a portionof the system being shown in section; Fig. 2 is a front elevation of thesame; Fig. 3 is a reduced plan view of a portion of the system; and Fig.4 is an enlarged plan view of one of the separating units with a portionthereof broken away to show the baliles.

I have found it desirable, in many cases in separating-.the moisturefrom the steam. or in purifying steam, to pass the steam first through aseries of baflies, against which the particles of moisture in thesteamare thrown, so as to break up the bubbles, particularly, when there ismore or less foaming in the boiler. This not only disrupts the moistureparticles, but it separates much of the moisture from the steam. Incarrying out my invention. I then pass the steam through a centrifugalseparator which is arranged to throw the remaining particles of moistureand other impurities outwardly away from the steam and thus to allow thedried steam to pass into the steam system without carrying with it anymoisture or other impurities.

The means which I prefer for carrying out this method of operation inthis instance comprises a bank or banks of baffles 10, which are adaptedto break up the bubbles or drops of water. This bank is itself a steamseparator and for convenience in this instance may be called the firstseparator.

F rom these ballle's the "steam passes 'through an outletll, which is anopening in a horizontal' pla-te 12' lmounted in the steam "dome Vlfl-tlie'i'bdile'i'. The pla-H312 entirely Separates the upper portion ofthe dome from the lower portion except vfor the outletpll; The steampipe la, together with the valvewop- @1j-anagrafi 15, pass'rhrough theplate. This 'rod l5 is' arrangclfo operate the? throttle valve 16 toallow the ste'amto pass inthe usual manner from the upl'aer end Iof thedome out into the steam` system of the locomotive. l

Iillfter the steam enters the upper chamber I7 ofthe dome it pases'through throttle valve 'I6 and the'l pipe .14;` into and through thecentrifugal 'separator 26. From this separator the steamand moisturepass into the casing 18 which has a chamber 19'.y The casing maybedesignated as the watercolflec'tor. In 'this chamber 19 la's'team outlet20 projects and from this outlet the steam passes to the steam main 2lof the system. In thelower portion of the collector the water from thecentrifugal separator collectsi as it is separated from the steam; and,

connected to this chamber is a drain pipe 22. The separated waterpassing into the drain pipe is carried out wherever desired through thepipe 23. And a vent pipe 24- connects the drain pipe with the chamber 19and prefvents clogging up of the drain pipe by relieving the backpressure and allowing any air or steam which may be entrained in thewater to pass back to the water collector.

Any suitable type of baffles maybe used in the first separator forbreaking up the bubbles. I prefer for the purpose the trough shapedbaffles 25 which are mounted vertically and through which the steampasses on its way from the boiler to the outlet l1.. By reducing thespace between the baffles sufliciently the steam passes through thesebaffles' at a very high vel-ocity and the bubbles are thus broken andcrushed against the sides so that the steam passing out of the outlet 11is substantially free from bubbles, and the drops of water arematerially broken up. A large portion of the moisture from these bubblesis separated from the steam while itis passing through these baflles andflows back into the boiler. The banks of baliles may be xed to the plate12, and may be removed with the plate for cleaning or other purposes.l

Any suitable type of centrifugal separator may be used for completelyseparating the moisture from the steam after it has passed through theseparator l0 and the throttle valve; I prefer tor the purpose thecentrif ugal separator 26, which has spiral-shaped conduits 27 soarranged that the steamand moisture as they pass through are given arotary forward movement; and as they pass out of lthe outlet 28 themoisture, and other impurities, being denser than the steam, are thrownoutwardly along. the inner surfaces of the water collector and pass downinto ,in the arrangement of the various parts or the details'thereof kbythose skilled in the art without departing from the spiuit of myinvention as disclosed by. the claims herein.

I claim as my invention: y Y 1..In a boiler system, `the combination ofa dome, a horizontal plate mounted in said .nected to. said dome, saidplate having an opening therethrough, a foam breaker mounted beneathsaid plate, said breaker having a steam inlet and a steam outlet, saidoutlet registering with said opening, a throttle valve mounted abovesaid plate', meansV for opening and closing said valve, a steamseparator mounted in said boiler, a pipe connecting said valve with saidseparator, and a pipe conseparator and passing out of said boiler. Y

2.* In a boiler having a dome, a horizontal plate mounted in theYCentral portion of said dome and having an opening therethrough, a foambreaker suspended from said plate, said breaker having a steam inlet anda steam outlet, the outlet offsaidbreaker registering with said opening,said dome having a detachable kcover thereon, a throttle valve mountedin said dome above said plate, means for opening and closing said Valve,said valve having a steam inlet and a steam outlet, a steam separatorlmounted in said boiler and having a steam inlet. and a steam outlet,communicating means connecting said valve outlet with said separatorinlet, and a pipe connected to said separator out let and passing out ofsaidY boiler'. h Ir testimony whereof,- I hereunto set my an Y f f HARRYE; Borana.
